# Image Compressor
Compresses images using best available tool (sips → cwebp → ImageMagick → Sharp).
## Script Directory
Scripts in `scripts/` subdirectory. `{baseDir}` = this SKILL.md's directory path. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun. Replace `{baseDir}` and `${BUN_X}` with actual values.
| Script | Purpose |
|--------|---------|
| `scripts/main.ts` | Image compression CLI |
## Preferences (EXTEND.md)
Check EXTEND.md in priority order — the first one found wins:
| Priority | Path | Scope |
|----------|------|-------|
| 1 | `.baoyu-skills/baoyu-compress-image/EXTEND.md` | Project |
| 2 | `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-compress-image/EXTEND.md` | XDG |
| 3 | `$HOME/.baoyu-skills/baoyu-compress-image/EXTEND.md` | User home |
If none found, use defaults.
**EXTEND.md supports**: Default format, default quality, keep-original preference.
## Usage
```bash
${BUN_X} {baseDir}/scripts/main.ts <input> [options]
```
## Options
| Option | Short | Description | Default |
|--------|-------|-------------|---------|
| `<input>` | | File or directory | Required |
| `--output` | `-o` | Output path | Same path, new ext |
| `--format` | `-f` | webp, png, jpeg | webp |
| `--quality` | `-q` | Quality 0-100 | 80 |
| `--keep` | `-k` | Keep original | false |
| `--recursive` | `-r` | Process subdirs | false |
| `--json` | | JSON output | false |
## Examples
```bash
# Single file → WebP (replaces original)
${BUN_X} {baseDir}/scripts/main.ts image.png
# Keep PNG format
${BUN_X} {baseDir}/scripts/main.ts image.png -f png --keep
# Directory recursive
${BUN_X} {baseDir}/scripts/main.ts ./images/ -r -q 75
# JSON output
${BUN_X} {baseDir}/scripts/main.ts image.png --json
```
**Output**:
```
image.png → image.webp (245KB → 89KB, 64% reduction)
```
## Extension Support
Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.
